Apache Subversion vs. OpenText ChangeMan ZMF vs. Perforce P4

It's a relatively simple version control system so it works great for an individual or small team (less than 10 people). But if you have a medium to large team, especially one with members distributed over a large geographic area, or one where individuals need to be able to work "offline" without access to a central server, Apache Subversion will likely not be the best choice.

Also, if you're maintaining an open-source project where outside people will be interacting with your code repository, git is probably a better choice because it's becoming the de-facto standard these days and what most developers are familiar with.

While Perforce Helix is the best version control software out there, it can also be used to track your documentation, training videos and materials, and requirements. If you have strict compliance requirements, it can be used to ensure that those requirements are satisfied. Perforce Helix is incredibly flexible and can meet the needs of individual users as well as companies with thousands of users.

Incentivized

• Revision control done properly - you have end to end visibility of all changes in the project.
• Conflict resolution - visually highlighting the differences helps to track down the problem.
• Being open source and very popular.
• We are using SVN hosted in our network - it is very stable, we had almost zero downtime in 4 years.
• Rollbacks are made simple and easy to use.

Incentivized

• The branching mechanisms in Perforce allow for an enormous codebase to be duplicated into release versions weekly with little impact upon things such as the speed of queries against the version control.
• Action triggers permit such things as automated builds of software versions, dynamic messaging when issues are identified either within or prior to a build process, and much more.
• Locking provides the ability to prevent modifications of stable, tested versions in order to ensure validity when they are released.

Incentivized

• Distributed development - I've never worked in an environment where distributed development (developers widely scattered geographically) was a factor, but that's why git exists.
• Merging - Merging of code from one branch to another can be painful, especially if it's not done frequently. (On the other hand, doing merges is one of the reasons I get a nice salary, so I can't complain too much!)
• Acceptance - Let's face it, git is what "all the cool kids are using." If you've got a bunch of developers fresh out of school, they'll probably know git and not Subversion.

Incentivized

• Perforce tends to feel backwards in how it approaches certain tasks, like branching and integrating - even once you figure out how it wants you to perform these tasks, you will likely forget when it comes around to the next time you need to do them again.
• Perforce has a higher price tag, comparatively.
• Perforce make some tasks very easy, and yet other tasks very difficult - it doesn't always seem to have found its target user's proficiency.

While there are interesting alternatives, such a GIT, Subversion has been a breath of fresh air compared to its predecessors like CVS or Microsoft Source Safe (now called Team Foundation Server). Its ease of use and high adoption rate is going to keep me using this product for years to come.

We are fully committed to our use of Perforce. It works well within our organization and our desire to share our code base with our customers. Their support staff are responsive, inquisitive, and eager to improve their software. I feel like we have a direct line to their design/feature team as they often solicit our feedback.

With Perforce Helix, you can use it via the command line, via P4V, or any of the other APIs included with the product. It is extremely easy for new users to get up and running. Users of Perforce Helix only have to pull in the files of interest to them. Also, Perforce is very easy to script and integrate into your CI/CD pipeline. Streams allows you to have pinpoint control of your workflow, and P4Search is the absolute best--I wish Perforce (the company) would talk more about this. It is absolutely fabulous!

In our large environment, Perforce is rarely "down". We have regular maintenance windows and from time to time Perforce can feel a little slow, but its always available. Tech support has always worked with our engineers and IT department to make sure that any real performance or stability issues are addressed quickly.

I had two representatives from Perforce contact me after downloading it but never responded when I had questions. I also had a difficult time finding good training material for getting started. There is a lot of available support material when running into issues, though, because of how many large companies use it.

This rating is related to setting up an environment from an existing Perforce repository. Initial setup of Perforce as the repository for the company was done by a separate team long prior to my inception.

Git has become the new standard of version control, with its support for distributed design. As a tool to manage and control versions, Subversion does it well, but Git is the future.

Incentivized

Git is great, I love Git. But it's not great for dealing with binary assets, even when using Git LFS. Locking is not as simple as on perforce. Git presents some problems on using for non-tech people it can get overwhelming and tech people have to come by and help.

Incentivized

• Subversion helps us feel secure in maintaining access to all of our product code, both current and historical.
• Being free and open source makes it an even better "investment".

Incentivized

• Decreased our implementation costs by allowing versioning and back out of customizations made in the field.
• saves developers time through automation of changes between branches - they think less of the plumbing and have more time to write code.
• Downside is training/managing expectations of new developers who come in assuming they will use Git.
